the axle of the vehicle respectively which are 1o caused to revolve one relative to the other under the iniuence of shocks received by the' vehicle wheel and radial members radiating from the tworevolving elements: in spa'ced and alternating relation with -r-cushioning l means illing 'the spacesv so that relative movement of the two elements Linvolies a compressing of the cushion means. It is further proposed to combine a featurerelying on frictional resistance with the cushioning l, feature. Further objects and advantages of the invention will appear as the 'specification proceeds. l The preferred form of the invention is illustrated in the accompanying drawing in which Figure 1 shows my shock absorber in side elevation, Figure 2 shows a vertical section taken along line 2-2 of Figure 1, Figure 3 shows an assembly view of my shock absorber in connection with the frame and and Figure 4a sectional detail view taken along line 4--4 of Figure-` 1t While I have shown form of the invention it should be understood that various changes or modifications may be madv within the scope of the claims hereto attaclied, without departing from the spirit of the invention.

@ne of the elements of my shock absorber comprises a hub portion 1 having two arms 2 radially extending therefrom which latter are adapted to be fastened to the frame 3' of a motor vehicle ing through perforations 6 in the arms and corresponding perforations in the frame. The -outer faces 7 of the two arms are arc sha ed and allow a ring 8 to revolve thereon which latter ring is the peripheral flange of a disc 9. This-disc is perforated centrally and rides on a reduced extensionjll of the held in place by means of a nut 12. The ring 8, has radial elements 13 extending inwardly therefrom in alternating and'spaced'relation with the arms 2 of the hub 1 and cushioning members 14 are A bracket 26 extendsfrom a.

only lthe preferred by means of bolts 4 extendinterposed between the arms 2 and the members 13, the cushioning members being preferably-made of rubber.

A second ring or band 16 surrounds the iii-st ring 8' and is yprovided with any suitable kind of brake; lining 1 7 the ring 16 being split as shown at 18 and provided with brackets 19 on o posite sides of the split which latter are orced toward one another by means of a spring 21 guided on a bolt 22 and compressed between one oi the brackets' 19 and a nut 23.

eripheral section of the second ring 16 and as a bolt 27 extending through the end thereof which latter terminates in a ball 28 `adapted to be received in a socket 29 in the standard 31 `which latter may be pivoted, as shown at 32 to a bracket 33 fixed te the axle 34.

My shock absorber operates as follows a A shock received by the axle through the wheels forces the extremity 26 upward and causes the two rings 16 and 8 to revolve relative to the stationary hub 1 whereby the cushioning blocks 14 are compressed, causinof the latter .to absorb the shock. In shoe s of minor nature the'cushioning members 11 absorb the entire shock and the relation between the two rings 8 of the bracket and 16 remains undisturbeddue to the frictionalresistance oifered by AThere a heavy shock is transmitted so that the cushioning members 14 reach the limit of their, compressibility the frictional resistance of the brake band lining is overcome sufficiently to allow the outer ring 16 to move relative to the inner one so that in such instances therewill be slight additional revolvin motion of the ring 16 besides that transmitted to the ring 8. The frictional resistance to the brake lining may be adjusted by means of the nut 28.

1. A shock absorber for vehicles comprising a hub fxedly attached to the frame of the vehicle, a plurality of radial arms integral with ythe hub, a drummounted for rotary movement about the hub and arms, inwardly extending segments on the drum and spaced between the arms, cushioning means filling thespace between the segments and the arms,` and means connected to the axle and frictionally engaged with said drum.
